二氧化氯在饮用水处理中的应用研究

对二氧化氯去除饮用水中微量有毒有害物质进行了研究。实验结果表明，二氧化氯具有很好的除酚能力，还能有效地去除色，浑浊度，锰，铁和阴离子合成洗涤剂等，是一种既可消毒杀菌又可深度处理饮用水的理想的消毒剂。纯的二氧化氯去除亚硝酸盐氮的能力较差，但使用副产臭氧，氯气和过氧化氢的二氧化氯可获得较好的效果。

Applied Study on Chlorine Dioxide in Drinking Water Treatment

The removement of microcontaminants from drinking water with chlorine dioxide was studied.The experimental results show that chlorine dioxide has a good dephenolizing capacity (the dephenolizing efficiency is 75% to 87% while the amount of added chlorine dioxide is 1 to 1.5 mg/L)and can also efficiently remove various contaminants of chromaticity,turbidity,iron,manganese and anion-synthetic detergent from drinking water.This proves that chlorine dioxide is an ideal sterilizer not only for disinfecting and bactericiding but also for deeply treating drinking water.Pure chlorine dioxide appeares a poor capability of removing nitrous nitrogen from drinking water,but chlorine dioxide combined with byproducts of ozone,chlorine and hydrogen peroxide can achieve a good result.
